There is a growing, but still controversial body of research that shows that all the exercise in the world won't protect your heart if you don't also eat well and, for some people, take drugs to overcome cardiovascular risk factors. Exercising too much may even raise the risk of developing clogged arteries, according to them. It's well established that moderate exercise has major benefits for heart health. When couch potatoes start moving, even by just walking three times a week, studies show that cardiovascular deaths drop by up to 25 percent and lifespans lengthen. Regular exercisers live an average of seven years longer than sedentary people. So the message is not that exercise is pointless. Instead, it's that you can't eat with abandon just because you're fit and slim. It may also be unwise to exercise with abandon, no matter what you eat.Exercise strengthens the heart, making it a more powerful pump and helping it become more efficient at turning oxygen into fuel. That kind of fitness boosts the chances of surviving heart attacks, illnesses and even car accidents. But working out does nothing to prevent the artery-clogging effects of eating a diet high in saturated fat, new studies suggest. That contradicts a long-held belief that athletics worked like a drug to protect the heart against atherosclerosis -- a build-up of plaque inside the arteries that can constrict blood flow and lead to heart attacks and strokes.

It's so sad that I only got to know about Maria de Villota today, when her mysterious death is on the front page of many news websites. She seemed like a pilot whose career I would really like to accompany. Maria was a Spanish racing driver. She suffered a severe accident during a test with a Formula One car from Marussia last season, in which she lost her right eye, and was still recovering from the injuries. Her ambitions were to get to the elite of world motorsport, but the accident ruined her pretentions. Since then, she gave speeches about transit security and life appreciation. She was found dead in a hotel room today and the cause of death is not yet clarified.

Scientists believe it has emerged in Europe more than 10 thousand years ago when humans had to cross frozen lakes in the icy winter. Archaeological findings confirm that animal’s bones were used as ice skates in places like Germany, Russia, Sweden, Scandinavia and Great Britain. Back then, the bones were tied under the feet by leather strings. The Dutch invented the metal blades to replace the bones in the 13th and 14th centuries, coupled to the shoes that were used in that time.

Researchers believe it arose from a ritual practiced in Angola (Africa), called "Zebra Dance". Brought to Brazil by the bantus in the slavery period, in the beginning it worked only as a demonstration of hability. With time, Capoeira turned into a game of atack and defense and its practice was forbidden. Nowadays, it is considered a martial art practiced without violence, as a game of skill.
